Comes with Different Capacities
Some electric water boilers come with different capacities, such as liters, liters, and liters, etc. The large 5-liters capacity is in fact more than enough for filling of multiple pots and several cups of tea, coffee, etc. Different water dispensers come with different features. A hot water dispenser offers a wide array of features and capacities. Large capacity water boilers are usually costlier than the ones with low capacity. You just have to determine your needs and get your hands on a particular boiler and that’s all.
Popular and trusted brands have small and compact design. They offer a lot of convenience and flexibility because of this feature. Unlike the other kitchen appliances, the electric water boiler and warmer occupy a very small space in the kitchen. You can easily place the device at any corner of the work area for later use.
Easy to Maintain
Maintenance constitutes a chief factor of any house-hold gadget. If any home appliance is difficult to clean and maintain, it’s just like a piece of garbage. The other main factor of hot water dispenser is its easy maintenance. These hot water dispensers are very easy to clean.
The internal non-sticky chamber and the 360⁰ rotatable base plate provide a lot of convenience and flexibility in their cleaning. Moreover, unlike the regular electric kettle, the hot water dispensers are very well-insulated. The steam of the hot water dispenser always stays inside the internal chamber and there is absolutely no risk of damaging the body parts.
The main concern of users is to avoid the wastage of water in low or dim light. A lot of companies are now offering their products with a night-light feature. This night-light feature allows the easy dispensing of water in the absence of an external light source.
The feature of de-chlorination significantly enhances the quality of water. Presence of chlorine results in unpleasant taste of water that can be avoided by de-chlorination. You can experience the real taste of a number of instant foods and drinks with this odor-free water.
In modern days, a number of hot water boilers come with quality insulation. Insulation just acts as the wall that provides the barrier between the internal and external temperatures. Just keep one thing in mind: insulation chiefly serves to preserve the warmth of the water. Well-insulated hot water dispenser can retain the warmth of water for several hours. So, you should go for such a product that offers better insulation.
If a water boiler lacks in proper insulation, chances are there that the required warmth of the water would not be retained. Just keep one thing in mind, i.e. the energy-saving mode of the device is heavily dependent on the quality of the insulation. If the quality of insulation is good, there would be more energy saving and vice versa.
Storage Tank Heaters
As the name suggests, these types of heaters store heated water and dispense it when required by the user. This is the first type of water heater that comes in a variety of sizes. These types of heaters usually operate by electricity, gas or solar panels.
The working of these water heaters is quite simple and easy. They keep the water inside the insulated container at a constant temperature. Refill water and reheat as necessary. Cold water is stored in the container where it is heated by a heating element at a constant temperature. This hot water is then risen to the upper portion of the tank, where it can be released as required. This water heater constantly works regardless of the instant need of the hot water. The average lifespan of a storage water heater is about 10-1years.
Tank- less Water Heaters
The tank-less water heaters are gaining more popularity across the globe. They do not require the storage of multiple gallons of water at a time. The main advantage of tank-less water heater is that it occupies less space than its storage tank counterpart and provides warm water immediately as required. Moreover, these water heaters are more energy efficient. This energy-efficient feature also results in decreasing the utility bills up to 20% as compared with storage heaters. The savings are quite noticeable.
The overall working of this heater is also quite simple and easy. Water enters the tank-less heater and passes through the heating element. This heated element heats the water immediately as the water passes through it. As compared to the storage water heaters, the price of these water heaters is 3-times higher. Also their lifespan has been increased by times.
Hot Water Dispenser
This is the third and last type of water heaters. These boilers usually look like a normal kitchen appliance. You will find them useful in the circumstances where you instantly need a hot water for several purposes. These water heaters come with different temperature options that can be used to prepare a number of instant foods and drinks.
Storage-Tank Water Heaters
Most of these are essentially steel cylinders fed by a cold-water inlet pipe (the dip tube) that protrudes into the tank (this line includes the shutoff valve). Water is heated in the tank, and hot water exits through a hot-water pipe atop the tank. Another pipe that emerges from the tank includes the temperature and pressure-relief valve, which opens if either exceeds a preset level. You’ll also find a drain valve near the tank bottom and a control unit outside for setting temperatures and, on gas models, controlling the pilot-light valve.
Gas is the fuel of choice if you already have natural-gas service or can run a gas line to your home economically. Gas models cost more than electrics. But on the basis of national-average fuel costs, a gas water heater will cost you about half as much to run as a comparable electric model. Thus, a gas heater might amortize the up-front difference in cost in as little as a year. While you’ll also find oil-fired storage heaters, they’re relatively expensive, because they include the tank and an oil burner. That’s why homes with oil heat typically use an electric water heater.
Tankless Water Heaters
Tankless models (a.k.a. instantaneous water heaters) are suitcase-sized units that heat water only when needed by using an electric coil (typically for low demand) or natural gas (for high demand) to heat water passing through a heat exchanger inside. They eliminate the risk of tank failure and the energy lost by constantly reheating water, though their heat exchanger can clog or fail. What’s more, they’re expensive to buy and install, and include limitations on hot-water flow rates, a possible issue in large households. And cooler incoming water in winter typically means your hot water may not be as hot as you like.
Hybrid Electric Water Heaters
These have a conventional electric storage heater paired with a heat pump that extracts heat from the surrounding air and uses it to help heat the water. Models we tested used about 60 percent less energy than standard electric heaters, which account for about half of all water heaters sold. And while hybrids cost more than electric-only models, installation is similar and payback time is short.
Solar Water Heaters
All solar water heaters supplement an electric heater in basically the same way: A roof-mounted collector absorbs the sun’s heat and transfers it to an antifreeze-like fluid in a closed-loop system that runs to the water tank. The collector is typically a flat panel or an array of glass cylinders called evacuated tubes. The best delivered stellar savings in summer, making them an attractive option for warm, sunny areas. But savings suffered on cold and cloudy days. And even with federal and local rebates, the thousands you’ll typically spend to buy and install one can mean you’ll wait anywhere from to 30 years before their savings pay for their costs.
Some brands–notably, Kenmore, State Industries, and Rheem–advertise features that are supposed to reduce buildup of mineral scale at the bottom of the tank by swirling the water. While scale can shorten the life of the heating element inside an electric water heater, you don‘t need to invest in fancy features to get a long-lived model. Simply look for a heater with a 12-year warranty, which typically includes a longer or thicker element.
Found mostly on hybrid and solar heaters, these help you monitor levels and customize operation. Some electric/heat-pump hybrid models let you digitally set a “vacation mode” that uses just the heat pump for added efficiency when you’re away. Displays on solar heaters often show tank and collector temperatures, along with pressure readings and other helpful data.
NATURAL & PROPANE GAS HEATERS
Pentair MasterTemp Pool Heater is designed with easy operation in mind. The straightforward digital, rotating display is complete with indicator lights makes for simple system operation. The compact design quiet operation makes for a discreet heater that will not be an eyesore near your pool area. It’s built to last with tough corrosion-resistant components can withstand exposure to low pH, high water flow, and heavy use-age. With a hot surface ignition it does not require lighting of a pilot light, and push-button, digital control panel is easy to operate. The MasterTemp incorporates PMG combustion technology giving it the a high 84% efficiency rating.
The Lochinvar EnergyRite Low Nox Heater combines long-lasting outdoor construction, energy efficiency, and digital accuracy that results in a high quality heater that offers high performance season after season. It’s 88% thermal efficiency rating certainly makes it the most energy efficient gas pool heater. It’s built to commercial grade standards and Lochinvar is a company that is known for their rigorous inspection process ensuring that every single detail is considered. The EnergyRite is rust-proof, with exterior surfaces molecularly molded with a porcelain and glass hybrid mixture that will not rust. The combustion chamber is fully shielded and windproof which also makes it spider and wasp nest proof.
POOL HEAT PUMPS
Let’s take a look at the Aqua Pro Heat Pump as it is one of the best available on the market in terms of efficiency and trouble-free maintenance. As I mentioned, after the initial purchasing cost, the Aquapro is the cheapest system to heat your inground pool, and includes features typically reserved for commercial grade heat pumps like a 100% titanium heat exchanger, automatic defrost (effective on temperatures down to 3degrees), programmable timer clock, and Pro Smart controls. The Aquapro heat pump is extremely quiet and a compact size makes it easier to hide than the larger pool heaters.
Another fantastic heat pump option, especially if you live in a cooler climate or intend on extending the length you plan on keeping your pool open, is the AquaCal Heatwave. It also features a titanium-built ThermoLink heat exchanger, is built to resist corrosion, sun-fading and rusting while producing higher heating power than most heat pumps. The AquaCal Heatwave is considered to be one of the quietest, user-friendly heat pumps available. It offers a surprisingly long list of features for such an affordable system making it one of the best values on today’s market. More on the AquaCal Heatwave here
SOLAR POOL HEATERS
The size of your pool, how quickly you want to heat the water, the temperament of your region’s climate, and how long you want to extend your swimming season are all important factors when determining what kind of heater you require. Budgetary concerns from initial set-up fees can often be curbed by low operational costs.
In such a feature rich market, it’s a difficult decision to decide on the best pool heater for you. If you have a nearby gas meter, a natural gas heater may be the best choice, or if you have a perfect sunny spot for mounting solar panels, that may be the way to go. And if you have neither, take a look at an electrical pool heat pump.
Electric Heating vs. Gas Heating
Diffen › Home Improvement › Appliances
Electric heaters are cheaper, easier to install and do not need a chimney like gas heaters do. However, gas heating has lower operational costs because gas is usually cheaper than electricity and gas heaters are better at warming up larger spaces. Electric heaters may be more economical when used in small rooms.
There are two kinds of electric heaters
Radiation heaters – A heating element that reaches high temperatures is packaged inside a glass envelope that emits heat as infrared radiations. A reflector directs the heat away from the heater. The radiation travels through air until it reaches a heat absorbing body. They provide spot heating. Examples of these types of heater is infrared heaters.
Convection heaters – Heating element heats the air next to it by convection. Hot air rises up and cold air rushes in to fill the gap and is heated. Thus a constant hot air current flow is setup. This is best suited for closed space. Examples of these types of heaters are ceramic and oil filled heaters.
This video talks about the different types of electric space heaters, theirs pros and cons:
A gas heater or furnace needs a chimney to send out the emissions due to the burning of gases. Installation generally requires air ducts and vents throughout the house. The heater itself is quite large and needs professional installation.
Portable electric heaters do not need installation. Wall-mounted electric heaters do need to be installed but the installation is much easier than gas heaters and can be done yourself.
The cost of installation of gas heaters is more as they need a centralized furnace with flue outlets to be installed. Electric heaters are comparatively cheaper.
Gas heaters produce more heat when compared to electric heaters in the same amount of time. Since gas is generally cheaper than electricity, a gas heater has lower operating cost. Electric space heaters are cheaper only when a small space is to be heated at lower temperature settings.
Gas vs. Electric Water Heaters
When it comes to water heaters, some of the same considerations apply. Gas water heaters are not 100% efficient and need to vent out gas via a chimney. There are some high-efficiency gas water heaters that do not require a chimney but use a fan and pipe to vent out via the side of the house. Electric water
Storage water heaters use a tank to store the hot water. These are different from point-of-use water heaters, which are smaller and installed in bathrooms where the hot water is needed. POU heaters are almost always electric while heaters with water storage tanks can be both gas and electric. Gas heaters are much more popular than electric water heaters in the United States and most European countries because gas is often conveniently piped throughout cities and towns and currently is the cheaper to use than electricity.

DeLonghi Kmix 5Ounce Kettle.
DeLonghi is another company with a long and distinguished pedigree when it comes to coffee and espresso makers. Their Kmix electric kettle isn’t quite as complicated or innovative as their coffee machines, but it doesn’t have to be. It’s simply a well-crafted and durable kettle meant to boil water quickly and it does that job extremely well.
There are no fancy controls or multiple settings for the DeLonghi. You put the water into its good-sized 5ounce (about six cups) kettle, turn it on, and it lets you know when your water has boiled – usually in just a few minutes.
This machine has the usual useful functions you’d expect: automatic shut-off, a concealed heating element, and cord-free operation. One smart addition to the Kmix is its removable lime scale filter, which will remove deposits and impurities from the water as it boils.
A major selling point of this electric kettle is its appearance. The inside of the kettle is stainless steel, but the outside is die-cast aluminum and can be purchased in any of eight designer colors: green, red, yellow, orange, magenta, blue, black or white.
The DeLonghi will not only boil water efficiently and safely, but add a real splash of color to any kitchen.
Adagio Teas 30 Ounce utiliTEA Variable Temperature Electric Kettle
Chef’s Choice 680 Cordless Electric Glass Kettle.
When you’d rather see how much water is in your kettle instead of trying to squinting through a small window, the Chef’s Choice 680 is your machine. It has a cool look to it, with its brushed stainless steel housing and black handle/lid/accents, in addition to the large (1.liter) glass tank.
There’s also no chance the water will be touching any metal or plastic which would add unwanted taste, since it only touches glass.
This model does not have any temperature adjustments controls; you just fill it with water and flip the “on” switch, and wait until the water boils. No mess, no fuss, and a price tag that matches. Unfortunately, there’s no signal to let you know the water has hit maximum temperature, but since you can clearly see when it’s boiling that’s not a major disadvantage. There is an automatic shut-off feature, too.
The Chef’s Choice is a powerful unit and brings water to temperature quickly. It doesn’t have some of the advanced features you can find in more expensive units, but most people are just looking for an electric kettle that works, and works well. This one does.

Convenience and Comfort
Add other advantages like automatic shutoff, grips that are usually more comfortable, materials that won’t rust (try to avoid plastic which can make the water taste funky), and the fact that you’d really have to try hard to burn yourself on an electric kettle, and you can easily see the arguments in favor of ditching grandma’s old tea kettle and going electric.
Target Temperature Functions and Auto Shutoff Features
As we mentioned earlier, the best electric kettles will allow you to select the target temperature for your water; the more settings there are, the more flexibility you’ll have. They’ll also either have a timer or automatic shutoff feature plus an option to keep your water warm, and their handles will be wide enough to grab yet cool to the touch.
Non-Spill Spout and Removable Power Cord
There are a few more features that are less obvious but should be considered. A non-spill spout will keep you from pouring near-boiling water over the counter or your hands, and a kettle that has a removable power cord or sits in a heated base will let you pour without having to worry about the cord getting in the way. Some bases now swivel 360° so you can turn the kettle to the angle that works best for you; that’s extremely handy for lefties.
Three months ago
For our 201update, we tested our previous top picks from last year against an additional seven kettles. And we have a new budget pick: the Hamilton Beach 40880 Stainless Steel 1.Liter Electric Kettle.
After testing four more electric kettles this year, we’re confident that the speedy, easy-to-use
Cuisinart CPK-1is still the best. We also recommend the for coffee and tea lovers, though it’s best for smaller households. If you prefer a cheaper option, we suggest the
A gooseneck kettle for pour-over coffee
Bonavita BV382510V 1.0L Digital Variable Temperature Gooseneck Kettle
We recommend this precise-aim gooseneck kettle for anyone preparing pour-over coffee, or for tea lovers who will geek out over its spot-on temperature accuracy.
Pour-over coffee lovers will appreciate the precise aim of the Bonavita BV382510V 1.0L Digital Variable Temperature Gooseneck Kettle. This smaller, 1-liter model is lightweight and easy to hold, so your hands won’t tire while pouring. Tea lovers will also like its spot-on temperature accuracy: You can set the Bonavita to any temperature between 140 degrees Fahrenheit and 21°F, so it’s ideal for brewing all varieties of tea. This model even has the ability to hold a set temperature for up to an hour, 30 minutes longer than our main pick. For larger households, we recommend the 1.7-liter version of this kettle.
Who should get an electric kettle
A variable-temperature kettle can heat water to the correct warmth for making delicious coffee or tea at home. Getting a variable-temperature kettle is the key to immediately improving your caffeinated-drink game, whether you’re a tea collector or a scale-grinder-dripper coffee nerd. If you’re not a coffee or tea aficionado, you may just want a no-frills basic model that only boils water. In either case, an electric kettle also works for people who hate the alarming sound of whistling kettles and want a fast, more automatic path to their morning cup of caffeine.
If the entirely plastic electric kettle you already own imparts an unpleasant taste or smell to the heated water, you may want to switch to stainless steel or glass. While these models still contain some small plastic components, they generally don’t have as many issues when it comes to producing a plastic taste or smell. To avoid plastic entirely, we’d recommend investing in an old-fashioned all-metal stovetop kettle.
How we picked and tested
In preparing tea, most people just put a kettle on to boil and then pour the resulting hot water over the tea bag, regardless of type or temperature. But the different varieties of tea are meant to be brewed at specific temperatures. While exact temperatures are up for debate and come down to personal preference (see The Sweethome’s suggested water temperatures for teas and coffee below), the general rule is that more delicate leaves require cooler water. So green tea, for example, should steep at a temperature markedly lower than the rolling boil that black tea requires.
A great electric kettle should have a wide variety of temperature settings to accommodate different types of beverages.
Coffee aficionados also pay attention to temperatures. The AeroPress system, for instance, suggests using water that is considerably cooler than freshly boiled: 17to 18degrees Fahrenheit. Some dripper owners use 19°F water while others suggest 20°F, and both of those temperatures fall under the full-boil temp of 21°F, too. A great electric kettle should have a wide variety of temperature settings to accommodate different types of beverages. Reasonable accuracy at hitting those temperatures is also important, because there’s no point in aiming for 200 °F and hitting 21°F instead. That said, we realize that not everyone is a coffee or tea aficionado, so we also looked at kettles that do not have variable temperature settings and simply boil water.
Even high-quality kettles have a somewhat short lifespan, so finding a model with a solid warranty is key.
Speed is critical—you don’t want to wait forever for your water to come to temperature. An electric kettle should also be easy to use, have a handle that doesn’t get too hot, and feature automatic shutoff so you don’t have to worry about forgetting to turn it off. A large mouth for easy cleaning is another plus, but these days the vast majority of electric kettles conceal the heating element, so you no longer have to contend with scale-covered electrical pieces that never get totally clean.
For 2018, we tested a new round of electric kettles for speed, accuracy, and ease of use.
Aside from technical features, we looked for models that came with decent warranties. Our research has shown (and customer reviews have indicated) that electric kettles have a high failure rate across the board. Boiling water is very hard on appliances, especially those with finicky moving parts or complex settings. Even high-quality kettles have a somewhat short lifespan, so finding a model with a solid warranty is key.
All of the kettles we tested for our 201update were metal or glass. Some people, including our experts, complain about plastic kettles imparting a funny taste or smell to the water. To minimize the possibility of unpleasant flavors in the water, we didn’t test any models made entirely of plastic. All of the models we did test, however, contained some minor plastic elements, such as parts of the lid, a filter, or the water-level window. All of the manufacturers of our picks assured us that the plastic components in their kettles were made from heat-resistant plastics; this means they’re less likely to leach by-products into your water at high temperatures, even after repeated boilings over prolonged use. Though glass kettles are less likely to impart off flavors to the water, they are more prone to breakage if dropped. In our experience testing kettles, we’ve found stainless steel models are more durable.
We tested the accuracy of the variable-temperature kettles using a Thermapen thermometer.
We tested each variable-temperature kettle by measuring how long it took to bring a liter of water to a boil and by measuring how accurate the internal thermometer was for non-boiling temperatures. We tested the internal thermometers by heating the water to one of the specific temperature settings (below boiling) and measuring it with a Thermapen thermometer, performing this test multiple times for the various temperatures available on each kettle (with ample time for cooldown in between sessions). For the simple electric kettles we tested, we just measured the time to boil. Some models in the test group had a warming feature that could hold set temperatures, so we checked their accuracy after letting them rest for an extended period of time. We also tested automatic shutoff features and took note of any excessive or annoying beeps. Additionally, we tasted the water from each model after boiling to see if it had any off flavors caused by plastic components.
Cuisinart CPK-1PerfecTemp Cordless Electric Kettle
This 1.7-liter variable-temperature stainless steel kettle quickly brings water to the temperatures needed for optimum flavor from teas and coffee.
Our top pick for the fourth year in a row is the Cuisinart CPK-1PerfecTemp Cordless Electric Kettle, thanks to its ease of use, speed, and accuracy. It has an intuitive interface with a keep-warm option that conveniently holds water at a set temperature. The wide handle is comfortable to hold, and the spout doesn’t cause water to dribble when pouring. Unlike many of the kettles we tested, it has a simple streamlined design, so it won’t be an eyesore if you store it on your kitchen counter.
Compared with all the other variable-temperature models we tested, the Cuisinart CPK-1was the simplest to operate. It offers six preset temperature settings as buttons on the handle (labeled as 160°, 175°, 185°, 190°, 200°, and Boil), along with a Start button and a Keep Warm button. You add the water, select the temperature you want, hit Start, and wait for the kettle to beep when it’s done. It then kicks into an automated keep-warm cycle, where it maintains the temperature for up to 30 minutes in case you can’t quite make it to the kitchen in time. In our tests the push button on the handle made for easy one-handed lid opening, and the water poured in an even stream without dripping.
The wide spout on the Cuisinart CPK-1poured water in an even stream without dribbling.
Aside from its straightforward, easy-to-use design, our testers found the Cuisinart had an extremely consistent boil time. On average, it brought liter of water to a boil in around four minutes. While the CPK-1wasn’t the fastest of the kettles we tested, it was speedier than most. Additionally, the Cuisinart proved to be impressively accurate in our tests: After it held a set temperature of 18°F for 30 minutes, the water measured just degrees over.
The Cuisinart proved to be impressively accurate in our tests.
The Cuisinart CPK-1also has all the other features we look for in an electric model, including a removable scale filter for easier cleaning, a concealed heating element that won’t get gunked up by mineral deposits, and a 360-degree swivel base so you can grab it from any angle. Its lid is large enough for you to get inside easily for cleaning (just avoid splashing water on the control buttons located on the handle). And while all of these features are fairly standard, the Cuisinart CPK-1is the only model we tested that offers them all while managing to avoid the glaring flaws that plague its competition.
Our top pick has six preset temperature settings as buttons on the handle (160°, 175°, 185°, 190°, 200°, and Boil), plus a Start button and a Keep Warm button.
In contrast to the annoying, excessive beeps that were one of the drawbacks of the KitchenAid KEK1722SX kettle (our former runner-up two years ago), the Cuisinart CPK-1beeps only once when you press a button on the control panel, or several times when it reaches a temperature setting. Our testers liked that temperature alert—it means you don’t have to hover over the kettle in eager anticipation. Be mindful, however, that a raucous beeping will occur if the kettle is on and you return it to the base empty. This is the “boil-dry protection” warning, intended to prevent damage to the kettle; just remember to shut it off if it’s empty. Since the water-level window allows you to see when it’s getting low, we found it easy to avoid this situation.
One feature the Cuisinart CPK-1has that makes it stand out is a limited three-year warranty, which is substantially better than what you get with all the other models we tested in this price range (most come with only one year of coverage). Given that constantly boiling water can be rough on a gadget, having triple the warranty coverage of the rest of the pack is impressive. For more warranty information or replacements, contact Cuisinart.
Flaws but not dealbreakers
Although the Cuisinart CPK-1had better accuracy than most of the other kettles we tested (which measured more than degrees off their temperature settings in some cases), we found it wasn’t as accurate at hitting lower temperatures, measuring degrees over when we set it to 160 °F. On temperatures of 17°F and up, it measured only to degrees off, which is pretty accurate. Since this model has a slew of other noteworthy features and has been consistently reliable over three years of long-term testing, we’re willing to forgive its minor temperature variances at the lowest setting.
Care and maintenance
To minimize the amount of deposit buildup in your kettle, always empty it after you use it. You’ll still need to decalcify your kettle from time to time, though the frequency depends on the hardness of your water. Check the manual for the manufacturer’s specific instructions on descaling; otherwise, you can fill the kettle with cup of white vinegar and cups of water, heat it to a boil, turn it off, and allow it to stand overnight. Alternatively, half a teaspoon of cream of tartar with half a kettle of water should also work. After emptying the kettle, refill it with water only, bring it to a boil, and drain; repeat twice more.
Some kettles come with a mesh filter for trapping calcium deposits, which you will need to clean periodically—more often if you have hard water. Follow the instructions in the manual for removing the filter, and clean it with a cloth or brush under hot water. For hard-to-remove calcium deposits, let the filter stand overnight in a solution of one part water to three parts white vinegar; rinse thoroughly before returning it to the kettle.
Mains pressure unvented
Unvented water systems have a hot water cylinder which is directly fed from the mains supply, without the need of a cold water tank. The water is heated by a boiler or immersion heater and has a strong pressure as it is coming directly from the main supply.
Cold mains supply
If you don’t have stored hot water or don’t want to use up the hot water when you shower, you can fit an electric shower to the cold mains supply. With an electric shower, the water is heated automatically when it’s switched on which means you don’t use up any hot water stored in a cylinder.
Mixer showers take both hot and cold water and blend them together for the desired showering temperature. They have three different temperature controls. With manual control, your shower temperature may vary depending on changes to the incoming water supply.
Pressure balancing mixers compensate for an imbalance in pressure between the hot and cold water supplies, providing you with a stable showering temperature. This is particularly useful for combination boiler installations which often have imbalances between the hot and cold supplies.
Thermostatic mixer showers are great for families with young children or the elderly as they monitor the incoming water temperature and adjust it to provide a comfortable showering temperature.
Mixer showers are ideal if you have lots of stored water from a combi boiler or large hot water cylinder and generally provide a faster flow than electric showers. If your home has a low pressure system, you can install a pump to increase the flow for a more powerful shower.
Power showers require a supply of both hot and cold water, which is then blended to the optimum temperature. They’re designed for low pressure gravity fed systems and are available in manual and thermostatic versions. Power showers have an inbuilt pump so are able to significantly increase the flow rate from a gravity fed system.
Power showers are a great option if you have low water pressure in your home but they can use a lot more water. This is important to consider if your home has a water meter or a small supply of stored hot water.
This type of shower needs a mains cold water supply only and heats water on demand. An element within the shower heats the cold water as it passes through the unit to the shower head, so it doesn’t use up any stored hot water. There’s no pump involved, so the amount of water will depend on your mains water pressure.
Ideal for families, electric showers are economical to run as you only heat the water you need, and they’re the only type of shower that’s independent of the hot water system, so if your boiler fails you can still have a hot shower.
The higher the kilowatt rating, the more powerful the water flow is – even at higher temperatures. This will usually range from between 7.5kW and 10.8kW. It is recommended to consult a qualified tradesperson when installing an electric shower as the size of the electricity cable feeding the shower will need to be assessed.
Digital showers allow you to set the right temperature and flow of your water from a control panel. If your shower has a wireless remote control, the control panel can be located within a metre radius of the shower which means you can turn the shower on and wait for it to warm up to the desired temperature before getting in. You can also pre-programme the water temperature to suit your personal preferences, giving you complete control.
There are two different types of digital showers: a low pressure variant which has an inbuilt pump as part of the valve and a high pressure variant. Which type of digital shower you choose will be dependent on your water pressure and system.
A processor box is connected to the shower’s controls though a wireless remote control and blends the hot and cold water supply to the required temperature using a digital thermostatic mixing valve. Water is delivered to the shower head through the riser rail, celling or wall, so there’s no pipes on show. The processor box can also be hidden so it isn’t on display within your bathroom.
Thermostatic temperature control
A thermostatic shower provide a constant water temperature, which isn’t affected by the use of other household items. This prevents spikes in temperature which could lead to scalding. Manual temperature control showers do not have this.
From clear and patterned to 3-fold and 4-fold, our range of shower screens offer great protection against water spray.
Boost the water strength and overall performance of your mixer shower with a pump. A pump is used to simultaneously boost hot and cold water supplies so you can enjoy a more powerful shower.

Storage water heaters
A storage or tank water heater provides a ready reservoir of hot water to be used.
It consists of a storage tank that holds up to over 100 litres of constantly heated water that can be dispersed throughout your home. When turned on, cold water is heated and stored, and reheated until needed. The storage water heater releases hot water from the top of the tank, and allows cold water to enter from the bottom of the tank to be heated, ensuring that the tank is always full. Since water is constantly heated, energy can be wasted, even when you are not using the water — so remember to switch if off after use!
For storage heaters, you have the option of electric-, and solar-powered models, as well as digital and heat pump ones. Heat pump and solar storage water heaters are eco-friendly choices, as they make use of renewable energy sources. A heat pump water heater takes heat from the surrounding air and transfers it into the tank to heat up water using a compressor.
Heat-pump water heaters, such as the Frankie from Ariston, are an eco-friendly chocie, as they efficiently heat a large quantity of water using a low consumption of energy by absorbing heat from the surrounding air. “Instead of using typically around 3000W of electricity, it uses only about 250W — meaning electricity savings of up to 7per cent!” says senior country manager Eddie Lee, of Ariston.
The latest models in the local market, however, are digital ones, which come with digital control panels that give you more control over the heater, making more efficient use of electricity to save energy.
Digital water heaters, such as those by American brand A.O. Smith, are equipped with control panels that allow you to adjust the thermostat to save energy.
Those by A.O Smith, available at AOS Bath, even come with a patented automatic energy saver, which is a memory chip that records your family’s usage habits to allow them to operate with the highest efficiency and lowest electric cost, says Amanda Zhong of AOS Bath.
A storage water heater can be installed in the ceiling (concealed with a false ceiling, for example), cabinet, basement or garage.
Instant water heaters
An instant or tankless water heater heats water directly on demand, without the use of a storage tank.
When you turn on the tap, water is rapidly heated to the desired temperature, as it flows through the unit’s heat exchanger. Energy is only used when the instant water heater is being utilised, which translates to more savings in the long-run. However, these type of water heaters generally have a higher initial cost.
For instant water heaters, you have the option of electric and gas.
Gas water heaters from City Gas are designed with built-in safety features and are also tested to EN2standard by TUV SUD PSB Singapore, an established and internationally recognised product-testing corporation.
According to information on City Gas’ website, based on an energy study conducted by Dr. Lee Siew Eang, an associate professor at the National University of Singapore’s department of building, gas water heaters are relatively more environmentally-friendly with 6per cent less carbon emissions as compared to electrical heaters. City Gas is Singapore’s town gas and natural gas utilities provider, and offers a wide range of gas water heaters, including those suitable for Housing Board flats.
As there is no water storage tank, it is also a space-saving option. Instant water heaters can be quite compact in design, and are commonly mounted on the wall, close to the point of use — for example in the shower area. But since it is exposed, it will definitely affect the aesthetics of your bathroom!
Instant water heaters typically have a lifespan of five to seven years, while storage water heaters last at least years. It is recommended that you perform tank flushing every five years for storage water heaters, and check the wiring every three to five years for instant water heaters.
See this guide to determine what water heater size you should choose.
Other clauses manufacturer attach are-
Conditions typically suffixed are- • Warranty void if not installed by a licensed electrician and plumber.• Warranty void if codes of plumbing violated.• Warranty void if found used for other purposes beyond the scope or a stipulated hour of use.
So what is the best? In my understanding ‘More the Merrier’ that is more years of warranty is better.It gives a sense of security for longer time and a conviction that the unit is designed for long years without complains. Longer years of warranty also come with strict and expensive conditions like-void in case of not installed by a licensed electrician and plumber. Such clauses simply ask you to spend 300-900 dollar extra. However if you are not an expert or have previous record of DYI skills you better not risk voiding warranty clause and hire an expert.
FHR ≥ 6gallons per hour
There are some other criteria like warranty to be higher than years on parts too and safety features. With such criteria this trademark is ensuring more energy efficiency. EF stands for energy efficiency. 87% EF means with unit of power consumption the heater transforms 87% of it into hot water and emission is minimal. Higher efficiency also signifies high environment friendliness.
Non condensing tankless water heater is the first generation of tank less units that give hot water on demand. They have Efficiency Factor 82%-85%. However the efficiency drops when used for short drops like-hand wash. They are well known in Japan and n Europe for their reliability, but the poor venting system of this type requires users to install additional stainless steel vents, costing some extra money.
Condensing tankless water heaters are the second generation of tank less water heaters. They have two heat exchanger one is same as that of non-condensing and termed as primary heat exchanger. Other one termed as second reuses heat the exhaust to further heat the water.It has higher efficiency of 92-94%. Also venting is inexpensive through PVC but it goes out weight by high unit cost. Like non condensing water heaters it cannot go beyond the lower efficiency for short water draws.
The third generations of tankless water heaters are called Condensing hybrid tankless water. They are most fond in USA. Though named as tank less it incorporates small – between liter and 2-gallon tank. This reserve is kept to resolve the inefficiency of high water consumption for short draws. On an average Efficiency factor is 94%, but it can reach up to 96% Efficiency factor. It also addresses the cold water sandwich too. With inexpensive PVC venting system So far these are best, however as it is still fresh in market fewer models and smaller companies with questionable warranty and quality issues.
Hot water only as it is needed
Unlike tank water heater who keeps running day long to give you hot water, this type only runs as senses a flow. So power consumption is 15-20% less. Tank less water heaters generate less energy losses associated with storage water heaters, it is as simple as the theory-run less use less power.
Low Fahrenheit and pilot light
If you set the heater for a lower heat set up it will also save more energy. Again if your heater incorporates a feature like pilot light it will consume power even when not working. This does trade-off some energy efficiency effect, so you need to decide if you need such feature or not. Even if it has this feature you can still save power by choosing to switch this option off while not in action.
In case of electric water heater a lot of emphasis is given on the capacity of the breaker. So do the stress test of the main breaker. Generally all amps have highest power up to the 80% capacity that they stand for.ie-if your tank less unit needs a 50-60 amp breaker you will need 60*1.20=7amp breaker or more whatever is available nearer to that value in market. So do the math and check if your existing breaker is powerful enough or you need a new one.
Check if the unit is heated and the manual • If the unit is heated you cannot install the unit• Check for manual instruction• Check in the electrical rating plate that shows voltage and wattage or you can look at product spec sheet. You should Consult Tankless manual if it is available• If manual asks for using a licensed plumber electrician and says your warranty will be void if you do it other way than you should consult a professional and get things done by them.
Know your desired Temperature
If you subtract the inlet temperature of your water from the temperature you desire to achieve than you get the temperature rise you are looking for.ie your required temperature is 15degree and your inlet water is 5degree. So the tank less water heater you are in need has to give a temperature rise of 100 degree.
Total Flow Rate
The most important thing to consider when looking at tankless water heaters is the flow rate that it can give you.
To understand why this matters, you need to have a basic understanding of the plumbing in your house. Each fixture, such as your shower, has a specific flow rate that it runs at. You will want to add up the total flow rate that you expect to use at one time.
Another important part of choosing a tankless water heater is considering what temperature it can heat to and how quickly. Have you ever taken a shower and been disappointed that the hot water didn’t last more than minutes? That was because of the water heater!
You can solve this problem by making sure that your tankless water heater has the right temperature abilities that you need.
To figure out what temperature rise you need, you should know what temperature the water that comes into your house is. Follow these steps to figure out what temperature rise you need:
Additionally, many tankless water heaters are rated to accept a wide range of incoming temperatures, which makes the buying process easier.
Gas Or Electric
Like many appliances, tankless water heaters can run on either gas or electric energy. What you prefer to use is up to you, but there are some key differences.
Gas tankless water heaters tend to be able to produce a larger temperature rise per GPM than electric models. If you need a very high temperature rise, you’ll likely want to look to gas.
You can usually get up to a 70°F water temperature rise at gallons per minute with a gas-run water heater. For electric, that temperature would only be possible at gallons per minute. Depending on your needs, one might be better than the other!
It is important to mention that there are more efficient electric water heaters than this average. If you choose a very efficient electric water heater, you can get a higher flow rate with a good temperature rise.
First of all thanks for reading my article to the end! I hope you find my reviews listed here useful and that it allows you to make a proper comparison of what is best to fit your needs and budget. Don’t be afraid to try more than one product if your first pick doesn’t do the trick.
